ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 2 large egg whites
• 1/2 cup granulated sugar
• 3/4 cup unsalted butter, softened and cubed
• 1 teaspoon vanilla extract
• Pinch of salt

directions

1. I place the egg whites and granulated sugar in a heatproof bowl set over a saucepan of simmering water.
2. I whisk constantly until the sugar completely dissolves and the mixture reaches 160°F (71°C).
3. I remove the bowl from the heat and beat the mixture with a mixer until stiff, glossy peaks form and the bowl feels cool to the touch.
4. I add the softened butter one piece at a time while continuing to beat.
5. I keep mixing even if the mixture appears curdled or soupy because it will eventually become smooth.
6. I add the vanilla extract and salt.
7. I beat for an additional 2–3 minutes until the buttercream becomes silky and fluffy.
8. I use the buttercream immediately or store it for later use.

storage/reheating

I store the buttercream in an airtight container in the refrigerator for up to 1 week. For longer storage, I freeze it for up to 3 months.

If needed, I gently warm the bowl for a few seconds to help restore its creamy consistency.

Why is my buttercream soupy?
